chkcrontab is a Python script to check crontab files like those in /etc/cron.d and /etc/crontab. It tries to catch glaring errors and warn on suspect lines in a crontab file. Some valid lines will generate warnings. Certain silly yet valid crontab lines will generate errors as well.

Run this by doing ./chkcrontab.py crontab_file

Errors will cause a non-zero exit code. Warnings alone will not.

To see sample output for a bad crontab, run the following:

./chkcrontab.py ./tests/test_crontab

See the ./tests/test_crontab.disable crontab for how to disable warnings and errors.
